To ALL WHOM 1T MAY GONCERN; I

Be it known that I, ANDREW V. SMITH, of San Francisco, county of San Francisco, State of California, have invented certain new and useful Improvements in Store-Trucks; and I do .hereby declare the following description and accompanying drawings are suicient to enable any person skilled in the art or science to which' it most nearly appe'rtains to make and use my said inventioner improvements without further inventionor experiment.

The nature of my inventionis to provide an improved store-truck, so constructed `that the wheels may be arrested, at the will ofthe truckman, while ascending or descending incliues.

In order to accomplish this object, I attach a roller transversely across the truck-,frame back of the wheels.

To each end of this roller is attached a brake. Abrake-bar, with a spiral spring beneath it, is connected to theA roller, passing upbetween the handles of the frame, on the end of which is placed a plate which workslagainst the truckman, lwhen he braces himself in going down inclines, and arrests the truck. A metal bar is attached to the side of the brake-bar, having a notch upon it which catches en ,a pin to keep the brakes in place against the wheels Below the handles is placed a movable cross-bar, operated by the hands of the truckman, by means of arms and leather straps, which lowers the brake-bar when loading the truck or passing up inclines.

To more fully illustrate and describe my invention, reference is had to the accompanying drawings, and letters marked thereon, of which- -Figure 1 is a side elevation. l

Figure 2 is a bottom view.

Similar letters of reference indicate like parts in each ofthe figures.

A represents a suitable truck-frame with wheels. Back of the wheels is placed transversely a roller, B. To each ofthe ends of this roller are attached brakes, C C, which may be ot' wood or any other suitable material. These brakes are held in place by metal wires or metal holders, D D, bent around the ends of the roller and brakes, forming springs, c c, for giving them elasticity. 4:Beneath the frame, and connected to the roller B, is a brake-bar, E, to the upper end of which is attached a plate, F. A spiral spring,lGr, is placedbeneath the brake-bar, one end of which is attached to the cross-bar ofthe frame by a band, through whichthe bar playa; the other end is fastened to the bar by a pin, d. To one side of the brake-bar is attacheda thin metal arm, H, by a pin and washer. This strip is bent near the in'side, forming a projection, which catches on a pin upon the inner side of the upper cross-piece of the frame, which sets the brakes against the wheels of the truck, while the opposite end forms a convenient handlelwithin easy reach ofthe truckman. As an auxiliary to the brakebar, a cross-bar, I, is placed transversely above the legs, attached loosely by bandsto the upper cross-piece of the frame. To the ends of this bai` arey attached curved handles, a a, and near them leather lstraps, b, the ends o'f which are fastened to the ends of the truck-handles. A ring, is also placed in the cross-bar I, near the centre of it, whichengages a projection, d', on the brake-bar, when the cross-bar I is turned or drawnup by the handles and leather straps.

Ingoing down an incline the truck can bc arrested by the brake-bar, by the truckman pressing back against Iit, and in passing up inclines, by the curved handles a a andr leather strapsb by pressing them up with the hands', thus saving at least 'the aid of extra hands, inpassing Vdown incline planes,r when thc truck is loaded heavily. Also, the wheels can be set, in loading the truck, so that it will not rollback.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The roller B, brake-bar E, brakes C C, holders D D, metal arm H, and springs c c, when applied to store-trucks, substantially as described, for the purpose specified. Y

2. The cross-bar I, handles a a, straps b b, ring b, Vwhen arranged and operated substantially as described, for the purposes specied. i

-In witness whereof, I have hereunto set my hand and seal.
